    A food chain shows how plants and animals are connected with each other based on the foods they eat.Food chains are different depending on the habitat.A habitat is the scientific name for a place where animals and plants live.Habitats can be very different from each other，so a garden food chain would be very different from a farm food chain.
    Food chains usually start with a green plant，such as grass or a tree.This is because plants can directly change sunlight into energy that they can use for themselves.These plants are called "producers"，and they create or produce their own food.They use this food to grow leaves，flowers，fruit and seeds （种子）.
    Food Chain Disruption （中断）
    When the balance （平衡） of a food chain is broken，it may result in a bad situation.An example I over fishing.Over the years，humans have been catching too many fish at a quick speed leaving not enough to keep a healthy population.Because of this，other animals such as the turtles are endangered.So，humanould make sure our activities don't harm the ecosystem （生态系统）.

C．asking questions
D．giving examples
（2）What can be best put in "        " in the second food chain？

B．Food chains usually start with human beings.
C．Different habitats lead to different food chains.
D．Plants are called "producers" because they produce food for others.

49632. （2024•阎良区•二模） ①More researchers are turning to artificial intelligence （AI） to monitor the environment and support endangered creatures （生物）.Unlike traditional methods that are harmful to the environment or require much time and physical work ，AI has the ability to quickly deal with large quantities of data （数据）.
   ②Creatures are disappearing at a speed thousands of times faster than that millions of years ago.The UN set a goal in 2020 to protect at least 30% of the Earth's land and oceans by the end of 2030."AI is 'imperfect' but could make important discoveries faster and earlier，"says Nicolas Mialhe，founder of The Future Society，an organization that aims to better manage AI."We need skilled humans to design AI models and check and collect data."
   ③A type of AI model called convolutional neural network （CNN） has been developed to recognize bird sounds.The CNN is able to pick out 75 kinds of the bird sounds."Our results prove that AI is ready for recognizing creatures in the wild from sound，"says Maller，the team leader，"All that is needed now is more training data collected by humans."
   ④Besides monitoring creatures in real time，AI can be used to model the influences of human activities on the environment.Researchers have used AI to discover how a century's environmental damage （损害） in a river has led to creature loss.Although it is well-known that human activities have resulted in creature loss in rivers and lakes，little is known about which activities have the largest influence."AI will do soon，"says Luisa Orsini，a researcher from the University of Birmingham.
